APIs are taking the world by a storm. As you strive to deliver world class web, mobile and SaaS applications, make sure the APIs that empower them are running smoothly.

AlertSite enables you to monitor your internal, partner or public APIs - REST or SOAP - effortlessly. Reuse existing SoapUI tests and monitor complex API transactions where APIs need to be invoked in sequence with the appropriate set of contextual data. 

API Availability, Performance and Functional Correctness

Ensure Complete API quality - Not Just 200 OK

  • Just checking if the API endpoint is responsiveness is not enough when your applications depend on APIs. AlertSite helps you test the actual functionality and speed of the API call.
  • Easily create advanced API monitors by reusing your existing SoapUI functional tests.
  • Monitor chained API transactions where APIs need to be invoked in sequence, and contextual data needs to be passed from one call to the next.

Monitor the Public or Partner APIs you Consume

  • You may not be providing APIs, but it is highly likely that your consuming them daily.  Services such as location or mapping are common third-party APIs that you might use.
  • What happens to your business if they are unavailable, slow or incorrect? Monitor the 3rd party APIs you consume and verify that they are returning right data every time. 
  • Detect API issues early on and hold your API vendors accountable.
